I wonder how something like this might process ambiguous phrases or metaphors, for instance, this passage in <i>Macbeth</i>:<p><pre><code> There's husbandry in heaven;. Their candles are all out.
</code></pre>
Because the word "out" can take on two meanings, and because "husbandry" refers both to putting out candles before bedtime and keeping a well-lit house, the sentence is a metaphor that means its own opposite at the same time. Compare:<p>1. "There's husbandry in heaven, the stars are all out on display."<p>2. "There's husbandry in heaven, the stars are all snuffed out."
